I discovered I could incorporate several activities I enjoy within a single hobby. I like spending time with my family and friends, solving puzzles, seeking out new adventures, exercising and being environmentally “green.” Geocaching is treasure hunting with a GPS receiver. You can search for geocaches online by zip code and download the coordinates into your hand held GPS unit. You seek out hidden geocaches based on longitude and latitude.

Sometimes the jackpot is as small as a prescription pill container with a piece of paper rolled up inside so you can log your visit. Some containers are so tiny; you need to bring your own pencil. Other containers are as large as a Tupperware[1] food saver or an army surplus ammunition box[2] filled with trinkets. Our geocaching equipment includes a bag of tchotchkes (swag[3]) that we swap based on the theme of the geocache.

For me though, the fun is not in finding the treasure, but the thrill of the hunt. We geocache while in Hawaii as an activity to challenge our brain and seek out new adventures.

This is a hobby that both family and friends can participate in. My husband and I often take others with us to introduce them to the hobby. We took keiki with us to the Honolulu Zoo[4] to find their first cache. When we returned to the island, their first question for us is “Are you going to go geocaching?” Other times we need subject matter expertise. One of the geocaches in the north shore required solving a puzzle to figure out the coordinates. Ten car logos were pictured from different auto manufactures around the world. After identifying the car model and country of origin, the digits of the location could be determined. I recruited a couple of world traveling gear heads to help figure out that one out.

While geocaching we learn about local history. A geocache is hidden on the estate of the last reigning Hawaiian monarch, Queen Lydia Liliuokalani. The site overlooks the drainage canal built to convert water logged taro fields into dry land becoming Waikiki.

A multi-stage geocache requires several stops. At each site you visit, you find clues to identify the next location. We learned about local leaders during a 5 stage history tour to five statues along Waikiki. Each statue had a plaque which told a story. There is Father Damien, who came from Belgium, to Hawaii in 1864. He devoted the rest of his life to the leper settlement on the island of Molokai before succumbing to the disease himself. He has been nominated for sainthood. During the 1893 overthrow of the Hawaiian monarchy led by U.S. business men, Princess Kaiulani spearheaded a campaign to restore the throne. Beloved native son, Duke Kahanamoku, born of Hawaiian royalty, was a swimming sensation earning 5 Olympic medals. “The Duke,” starred in Hollywood movies and is known as “The father of modern surfing.”

You can get a good workout in a day hiking up Diamond Head, the extinct volcano which stands at the east end of Waikiki. If you have comfy shoes, cache your way around the volcano on foot enjoying a heart healthy work out and spectacular views of the Pacific, Waikiki and downtown Honolulu.

Get away from the crowds and cache in Kailua. There are finds along both the busy and the quiet parts of the beach. Don’t forget your sunscreen and snorkel gear. You’ll be hungry after a day of swimming and caching. Check out the yummy handmade cookie store in town for a snack.

When you are on Oahu, you don’t have to go far to find these treasures. There are hundreds of local finds. From the crowded pedestrian malls of Chinatown to the top of Diamond Head to the shores of Kailua, there is a cache for every interest and ability.

While we are getting our exercise, learning about the area and catching up with friends and family, we also pick up trash[5]. We carry in a couple of empty garbage bags to snatch up any litter we spy while we are out. This is referred to as “cache in, trash out[6].”

You can learn more about the hobby at geocaching.com[7]. I enjoy the opportunity to combine time with my family, brain exercise, and physical activity all in one hobby. If you like history, culture and the great outdoors, you should give geocaching a try.
